DayView doesn't rebuild when changing content.

[kuemme01]

Describe the bug
The DayView widget doesn't rebuild after changing content via state.

Code snippet

Widget _buildDayView() {
    List<FlutterWeekViewEvent> meetings = selectedWeekDay.meetings.map((meeting) {
      print('Meeting: ${meeting.title}, date: ${meeting.startDate}');
      return FlutterWeekViewEvent(
        title: meeting.title,
        description: meeting.description,
        start: meeting.startDate,
        end: meeting.endDate,
      );
    }).toList();

    print('Meetingscount: ${meetings.length}');
    print('SelectedDate: ${selectedWeekDay.date}');

    var dayView = DayView(
      date: selectedWeekDay.date,
      events: meetings,
    );

    print('DayEvents: ${dayView.events}');

    return dayView;
}

Console

- I/flutter ( 8800): Meeting: Meeting 1 , date: 2020-02-17 10:00:00.000
- I/flutter ( 8800): Meeting: Meeting 2 , date: 2020-02-17 11:00:00.000
- I/flutter ( 8800): Meeting: Meeting 3 , date: 2020-02-17 13:00:00.000
- I/flutter ( 8800): Meetingscount: 3
- I/flutter ( 8800): SelectedDate: 2020-02-17 00:00:00.000Z
- I/flutter ( 8800): DayEvents: [Instance of 'FlutterWeekViewEvent', Instance of 'FlutterWeekViewEvent', Instance of 'FlutterWeekViewEvent']

After changing date via state:

- I/flutter ( 8800): Meeting: Meeting 4 , date: 2020-02-18 10:00:00.000
- I/flutter ( 8800): Meeting: Meeting 5 , date: 2020-02-18 13:00:00.000
- I/flutter ( 8800): Meetingscount: 2
- I/flutter ( 8800): SelectedDate: 2020-02-18 00:00:00.000Z
- I/flutter ( 8800): DayEvents: [Instance of 'FlutterWeekViewEvent', Instance of 'FlutterWeekViewEvent']

Expected behavior
DayView should rebuild its content.

When I remove the widget via code and add it again, it has the new content.

I think it's because the state is creating a copy of events (which allows to reorder them and to place them in the stack).

This should be managed in didUpdateWidget. Will take a look at this.
